My inventiom-ss its name indicates, re-

lutes to the class of devices used for lilling cans.

- While the device is especiell use in supplying gritty materiel lupted for o, more or less liquid or plastic form, yet it is not limited to such use.

The. object of the invention is to provide t can filling machine that shell be extremely durable and eflicient in operation and not subject to undue wear by reason of the pres ence of rit-t Y materiel oein o ercted u 301 ?3 lb I and a further ohject of the invention is to provide it device of this class arranged to successively supply the required quantity of material tothe cans to be filled; and e further object of the invention is to provide means whereby the proper quantity of materiul maybe supplied to cons 10f different capacity. 7

A form of device in the use of which those objects may be attained is illustrated in the accompanying drawings in which I Figure 1 is av view in elevation, partially in section, of o machine embodying my invention. Fig. 2 is a View in section through the some on a plane passing through the axes o1 pivots of the compressor arms.

I have fpund from extended experiment that in the; employment of machines for ha-ndlin grittysubstances, and especially such suhstances in a more or less liquid or plostic'form, thst Where purtsare in movable contact with each other end also in contact with the substances operated upon, such ports soon become Worn from the action of the grit to'an injurious extent, and in the device herein illustrated and described I hove so constructed the ports that there is no movable contact between the parts innuedietely in'contoct with the material operated upon, the-wear having thus been reduced to o minimum.

In the accompanying drawings the nu nierul 5 indicates delivery spouts located at the'lower end of s reservoir odaptod to contain the muterial to be supplied to the cons being tilled. This reservoir may he constructed of any suitable meteriul and form and any number of spouts mr n'ojeot therefrom, two only, however, hens; shown herein, end the description in gsjouerul, or solc of brevity, while referring to only one spout will he considered as i plying equally to both. A neck (3 projects from the lower end of the spout und in this norlr u valve seat 7 is formed facing downward. A valve support 8 extends across the lower end of the spout and u vulve stem t) heuring u valve 10 is mounted .in this support. A spring ll thrusting against e. si stem holds suid vulve uguinst its soot.

A measuring device is opr-rutivcly located with respect to'tho lowcr end of the spout and neck, this measuring device ronsisting "briefly of a holder and compressors with their operating mechanism. The holder 1:) is preferul'ily formed to be flexible-sud nonelastic. It may be constructed of u mutcrizil having non-elastic qualities and properly lined to be impervious to the nurterlnl to be contained therein, or as shown muy be formed of Webbing closely woven. to he impervious to suid mutoriul. This holder is secured to the neck 6 in on suituhlv manner and depends therefrom. to the lower end of the holder ullords means for outflow of tho materiul l'rom the holder. This month is constructed so that the lips are normally closed against eurh other with a force sulliriont to resist the natural pressure of the material within the rrsru'wir and holder. In the form ol construction herein shown a throat piers l3, prol'oruhly rou structcd oi comporartiroly thin. metal, and of rectangular form, is serurod to the open end of the holder and :1 month pivro 14 tuporing in one direction to the lips 15 is secured to the throat piece. constructed that the lips 15 uli normally forced in contact each with the other.

Compressor arm pivots in are mounted in bearings or curs 17 projecting from the spouts 5 and compressor"arms lo, sorurod to said pivots, extend (l(' \\'l1t\'zil'(l supporting compressors ll). in the form of ronstrurtion heroin shown ouch romprossor has a threudedshonk 2t) engaging a thro-(tded opening through u. compressor hearing 21 on the end of the urm l8, u lorh nut 22 being employed to hold the pull-ls in 'iolstion. From this construction it will be noted that the oulder on-lhu vulve' A month secured This moul'u plow is so compressors may be so arranged as to compress the holder to a greater or less extent, thus graduating the amount of materlal which -Wlll be delivered from the holder 1n each movement of the compressors toward each other, and thus accommodating the machine to the filling of cans of different capacity.

4 it will be noted that the com ressors appurtenant to the spout at the rig it of Fig. 1 are arranged in .closer proximity than are the compressors appurtenant to thespout at the left of said figure, this being determined by the distance between the back of the compressors and the edge of the bearing 21. The result will be that less material will be supplied from the holder appurtenant to the spout at the right of said figure to fill the cans a. of smaller capacity than will be supplied from the spout at the left of the figure to fill the cans b of larger capacity.

A compressor lever 23 is secured. to the pivot 16 and is connected by a link 24 with an actuator 25- mounted on a pivot 26. There are two of the links 24, thcselinks being adapted to operate the. compressors on opposite sides of a holder. A connecting rod 27 extends between the actuator 25 and a crank 28. This crank is a double crank, as shown in Fig. 2, mounted in bearings 29, a connecting rod 27 extending from each crank to an actuator 25. These cranks may be operated from any suitable source of power, a gear 30 having been shown here as the means for receiving such power to trans mit it to the crank.

Shaft-s 32 are suitably mounted in the frame of the machine, these shafts bearing drums 31 supporting carriers These carriers are arranged to support the cans a and b and deliver them at proper intervals to re ceive materials from the holders. 34 is employed for imparting movement to the drum 31* supporting the carrier on which are mounted the. cans b and a sprocket chain 35 extends-to a sprocket 36 carried by a shaft 37 properly mounted in the frame of the machine. This shaft also carries a ratchet 38 in connection with which a pawl 39 secured to a pawl lever 40 is arranged. The pawl lever is operated by a rod 41 secured to an arm 42 upon the connecting rod 27 appurtenant to the holder for filling the larger cans. The drum31 mounted upon the shaft 32 and supporting the carrier 33 for delivering the smaller cans a has a gear 43 secured to the shaft 32, this meshing with a gear 44 upon a shaft carrying a sprocket 45. A sprocket chain 46 extends to the sprocket wheel 47 mounted to rotate with a ratchet 48 having .1 pawl 49 mounted on a pawl arm 50. A rod 51 connects the pawl arm with the connecting rod 27 for operating the compressors for filling the smaller cans a.

A. sprocket The operating mechanism extending be tween the compressor operating mechanism and carriers has been omitted from Fig. 2 for sake of clearness.

the means of the connecting mechanism, the carriers are timely operated in connection with the compressors to place a can underneath a mouth from a holder just before action of the compressors to force the material from the holder, and to remove the can from underneath such mouth during the backward movement of the compressors.

It will be noted that the mechanism as shown in the figures, and especially in Fig. 1, is in a position with the holder nearly but not uite filled, the material'still running from t e reservoir into said holder, thus. maintaining the valve in its open position.
